What it does
You pick any time-sink site
Next visit, Focuser asks, “Do you really need this site?”
If you tap Yes, you must 1⃣ Write why you need it 2⃣ Choose exactly how long you need access
This 20 second friction is based on Shawn Achor’s habit-formation research
Why it’s different
Runs 100% client-side—no analytics, no external calls
Uses Manifest V3 already (future-proof for June 2025 Chrome deprecation)
Works offline
Settings live in localStorage
Ask
